The cally disclosed and wherein like referencecharexpansion and contracting links vi5 are pivoted acters designatecorresponding parts throughout to the upper slide 23 and said slide islocked the views: 7 against upward movement by alock nut 26 on a aFigure l is fragmentarysectional end. elethe threaded part of the; rod.'A similar ad- '55 v'ational view showing a portion of the chimneyju'sting and retention nut 21 onthe threaded rod cooperates with theslide 24 to regulate its position. A pair of shorter links 28 arepivoted to the intermediate portions of the links 25 and function as atoggle unit. The lower ends of the adjusting and supporting links 25 arepivotally connected, with diametrically opposed clips, these beingshaped to engage over the pipe 29. The vclips are. employed in'pairsdenoted by the numeral .30 and aresecured by bolts or the like'sl to thepipe.

It will be noticed that "the-screw-threaded rod is provided withvertically spaced holes 32 to accommodate locking pins 33 and 34, theupper pin 33 coacting with the bracket. l2 and the. e lower pin 34coacting with the slide 23. The pins can be placed in the desired holes.32ydepending on the size of the pipe ongwhich the fixture 20 is adaptedto be mounted. Obviously, the pin 33 servestointerconnect the hood andspindle to maintain the parts assembled. The toggle and nut arrangementserves to-adj ust-tlie links 25 to, in turn, adjust the clipstll toadapt the fixture 20 to the chimney pipe 29;" Consequently, this deviceis suitable for pipes of Varying diameters.

Somewhatthe same generic arrangementvis shown in the modification inFigures 6 to"-9.- Here the rod 35 has its upper end formed into aspindle 36 provided with an assembling pin 31.; A plate is, disposedbetween the' binding nuts 38 and 39 and providesa support for thehingedly mounted links 40. The links 40 are pivotally attached as at '4ltoUeshaped clips 42 which "saddle over the pipe 29, beingattachedthereto' by suitable fastening 43.

It is thought that the description taken in? connectionwith the drawingswill enable a clear understanding of theinvention to be had. Therefore,a more lengthy description is thought-un fy necessary.
